Thank you Peter,

I'm going to remove the 4 last patches from the pull request and resend it.

Thanks,
Laurent

Hi. This breaks one of my linux-user smoke tests:

/home/petmay01/linaro/qemu-for-merges/build/all-linux-static/sparc32plus-linux-user/qemu-sparc32plus
-L ./gnemul/qemu-sparc sparc/ls -l dummyfile
unable to find CPU model 'Fujitsu MB86904'

This is because the include path for linux-user picks the
guest-architecture subdirectory for the TARGET_ABI_DIR,
which for sparc32plus is "sparc", but the set of CPUs compiled
in depends on the TARGET_ARCH, which is "sparc64", and
sparc64 doesn't include that 32-bit Fujitsu CPU.
The linux-user/sparc/target_elf.h needs to have code to handle
both the pure-32-bit and 32-bit-ABI-on-64-bit-CPU cases,
the same way that linux-user/ppc/target_elf.h does.

thanks
